Notes and facts about the book:

This is the sixth book in the series. In the Lexicon, its abbreviation
is HBP.

When Rowling first put the title on
her website it was written
"Half Blood" Prince. Soon afterward she changed the title on her site to
the more grammatically correct "Half-Blood" Prince, which is how
it was published.

Rowling's comments about the book:

Aug 15, 2004:

At the moment, I really like how the sixth book is going. A lot happens in
the sixth book and a lot of questions are answered. I really have a sense
that we are nearly there and it is time for answers, not more questions and
clues, although obviously there are a few clues as I am not quite finished
yet. I hope that that is sufficiently frustrating for you, knowing that you
can't read it yet! (EBF)

I have come close to using a chapter very like this in
Philosopher's Stone (it was one
of the discarded first chapters),
Prisoner of Azkaban and
Order of the Phoenix but here,
finally, it works, so it's staying. And that's all I'm going to say, but
when you read it, just know that it's been about thirteen years in the
brewing.
